What I want to do is show the data that I put in my textBox on my page first I send them to a class called people, I keep them in a ArrayList and then I consult them to be shown by a REGISTER method that is in PersonaBean in a dataTable with the register button. The problem is that when I give it to register it does not show them on my page. I put the code below!
